This invention is an oil can of the type commonly known as squirt oil cans.

@ne of the objects of the invention is to provide an oil can of the type mentioned, constructed of a minimum number of parts so assembled as to avoid the employment of soldered or welded joints. A further object is to provide a simple means for operatively mounting the force pump in a position to be conveniently operated. A. further the can body which is provided with a bottom 11., and a false bottom 12. The said false bottom is spaced from the cam bottom 11 to provide a supplemental chamber 13 in the lower portion of the can. The contiguous peripheral edges of the false bottom 12 and of the permanent bottom 11 are jointed with the lower edge of the can body 10 by means of a pressed or rolled joint indicated at l t, the edges being folded or rolled together in a manner well known in the metal working art, to provide a liquid tight permanent joint. The false bottom 13 is provided with a centrally located opening 15.

The upper end of the can body is provided with a contracted neck portion 16, provided with a rolled screw thread portion to receive a correspondingly threaded cup-like closure 17. Depending from the bottom wall of said closure is a pump cylinder 18, the lower end of which projects through the opening 15 in the false bottom 12, and is provided with an inlet opening 19. Cooperating with said opening is a check valve 20, which is normally held to its seat by means of a spring 21, reacting against a plate-like abutment 22, provided with legs engaging the wall of the cylinder 18 to retain it in place. An inlet spout 23 is connected to the lower end of the pump cylinder 18, and extends from the opening 19 to a positionnear the bottom of the chamber 13. 1

The pump piston 25 may be of any suitable structure, and is normally held in a raised position by means of a spring 26 which reacts against the abutment 22 and one face of the piston. A piston rod 27 extends through tubular guide 28 formed in the closure 17, and is provided with an offset portion 29 to be engaged by the thumb or finger of the operator to depress the piston 25. The spout 30 is also secured to the bottom wall of the closure member 1?, and its lower end is con nected with a feeder tube 31 leading to the lower end of the pump casing.

Owing to the fact that the closure member 17 will not always come to the same position, a special form of handle is designed to grip theneck 16 of the can, as shown, so that the can and handle may be relatively rotated to bring the offset portion 29 to a proper position to be conveniently reached by the operator. As shown in the drawing, the handle consists of two strips of metal having abutting portions riveted or otherwise secured together as indicated at 32 and 33, respectively, the intervening portions being spread apart as indicated at 34; to provide a grip. The upper ends of said strips are offset at an angle and bent to form a circular split collar portion 35, adapted to embrace the can neck 16. i

In practice, the can body may be constructed in the ordinary way employed in metal working, the can body 10, the bottom 11, and false bottom 12 being united in a manner to produce the rolled or pressed joint 14. The screw thread in the neck 16 may also be formed in any well known way. The pumping unit including the pump cylinder and its piston, the inlet spout, the delivery spout and the closure 17 may then be inserted in place by merely engaging the closure 17 with the neck 16, the opening 15 in the false bottom 12 permitting a flow of oil from the main body of the can into the chamber 13. The operation will be readily apparent from the drawing. Reciprocation of the piston eventually draws oil out of the chamber 13 and forces it from the delivery tube 31 and spout 30, in such quantities as may be desired, the oil being delivered by a direct positive pressure applied thereto.

The advantages of the invention are that all of the parts of the can body are united together by rolled or pressed joints, which provide a thoroughly liquid tight union of the parts, without necessitating the use of soldering or of welding operations. It will be also noted that the force-feed elements are constructed as a single unit and may be insortedinto the can or removed therefrom at will.

Having thusexplai-ned the nature of the invention and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is 1. An oil can comprising a body provided at its top with a centrally disposed neck, means providing a supplemental chamber in said body, a cup-like member removably mounted in said neck and having a bottom wall constituting a closure, a spout attached to and supported by said bottom wall, a pump cylinder open at its upper and lower ends, said upper end being secured to said bottom Wall, its lower end extending into said sup lemental chamber, a piston working in sai pump cylinder, and a feed tube connecting said cylinder with said spout.

2. An oil can comprising a body provided at its top with a centrally disposed neck, means providing a supplemental chamber in the lower portion of said body, a cup-like member reanovably mounted within said neck and having a bottom wall constituting a closure, said closure having an opening therein, a spout attached to said bottom wall, a pump casing, having an upper open end, the edge of which has a rolled engagement with said opening, the lower end of said pump being open and extended into said supplemental chamber, a piston working in said pump casing, and a feed tube connecting said pump casing with said spout.

3. An oil can comprising a body provided at its top with a centrally disposed neck, means providing a supplemental chamber in said body, a cup-like member removably mounted within said neck and having a bottom wall constituting a closure, said bottom wall having an opening therein, a guide sleeve supported y said cup-like member in a position concentric with respect to said opening, a spout attached to said bottom wall, a pump casing having an open end, the edge of which is secured to the edge of said opening, the lower end of said pump casing extending into said supplemental chamber, a feed tube said handle having separated ends embracing said neck, the other arm having a spread apart portion providing a grip.

In testimony whereof I have hereunto set my hand.
